Re: PLL

2008-02-29 by nakedintruder

Lately I've been having a lot of fun trying to lock to clipped and volt-rotted signals coming 
out of the BBD module. Try putting something that's really squared off into the BBD (I use 
the low outputs of the Zorlon Cannon), take the signal out of the BBD out jack, put into the 
"signal in" of the PLL. 

Next, patch a slew limiter (the more control you have over rise/fall/response, the better) 
between the phase comp out jack and the vco CV in jack. Play around with the input 
signal, bbd clock, and the slew parameters until you get a signal you like out of the PLL. 
The slew in place of the onboard LPF gives you much finer control, you can dial in a wide 
range of tones this way. 

At high BBD clock rates with this patch (at least with my 1024) when the pll is in mid or 
high, mode 1 or 2, there's some really nice crud in there when it loses lock on the signal 
and tries to find its way home. 

One of my favorite modules ever. There are a million different things you can do to patch 
out the normalled routing and many things result in delightful audio garbage. I just 
discovered that patching in the Zorlon (which has a linear freq control) in place of the 
PLL's onboard VCO yields great results in mode 3.. strange things happen when you try to 
get the short pseudorandom sequences to lock to a better-behaved external signal.
